Spawning Script Error

Here are my 2 scripts I am trying to create to make my Game object Spawn to a certain place, But I am getting this error.

Assets/Checkpoint.js(8,42): BCE0020: An instance of type 'UnityEngine.Transform' is required to access non static member 'position'.

Here is the first script for the checkpoint system:

 ----------------------------------------------------------------------------------------------

 #pragma strict

 static var  ReachedPoint : Vector3; 

 function OnTriggerEnter (col : Collider) 
 {
 if (col.tag == "Player")
 {    if(UnityEngine.Transform.position.x > ReachedPoint.x )
 {
         ReachedPoint = transform.position;
     }
     
 }
 
 }

 ----------------------------------------------------------------------------------------------

here is the script for the Ball Health system that uses the Checkpoint Script:

 ----------------------------------------------------------------------------------------------

 #pragma strict

 var maxFallDistance = -10;
 private var isRestarting = false;

 function Update () {

 if(transform.position.y <= maxFallDistance)
 {
     if (isRestarting == false)
     {
         RestartLevel();
     }
  
  
  }    
 
   }    
 
  function RestartLevel (){
  isRestarting = true;
  //Application.LoadLevel("Level 01");
  transform.position = Checkpoint.ReachedPoint;
   }

 ----------------------------------------------------------------------------------------------

Do any of you know how to fix this error? Or what is wrong with any of the scripts?
